What fingering are you using on the last beats? If it's one rotation at the stretch of the hand, I'm not sure that's practical. If you switch to the thumb midway through (1,3,1,5 on the first, for example), I don't think it will destroy the slur, and it appears much easier. Just me cents two.
I wouldn't advise that. Doing that takes your LH thumb away from where it's going and it will be more difficult to connect with the first beats. Plus it seems like doing that would make note memorization more difficult as well.As amelialw said, the most important parts of this section are the 1st and 4th beats. I know you were just making a recording to demonstrate tempo, but I would advise that after the first beats, cut the dynamic down and give it a nice cresc as marked. Also, the LH has a beautiful descending chromatic melody going on, so think about connecting that melody and the rest might become easier. Eventually it should move a bit more, but work on solidifying it first.
You may have also learned a wrong note, so check that too while you're at it...First measure, 4th beat, LH... the F is still double sharped.

Alright, thank you. I'm also assuming that the tempo is fine. I'll just have to be patient solidifying process. Also, can you explain what you mean by "connecting [the] melody" of the descending chromatic melody? Is it too blurred out?
I just mean that with Rach, you always need to look for the inner melodies, and bring them out. The tempo is on the slow side, but fine if you're still learning it.
